5 Aminotetrazole Monohydrate Lab Report

The percent yield was calculated to be 129.7%. This high percent yield resulted from the presence of

Suppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$

Testing phase finds differences in positive/negative documents by the centroid obtained in training phase by ranking each of them. The simple way to estimate similarity between documents and centroid by summing weights of patterns which are in the documents. VII. Experimental Results To determine accurate measures of similarity or difference between documents you depict results by graph pattern and table pattern. The experimental setup consists of relevant documents that you termed as positive and negative documents .i.e

Sodium bromide and 1-butanol are dissolved in water since the bromide ion from the sodium bromide and the four carbon chain from the 1-butanol are the desired components of 1-bromobutane. In order to get the sodium bromide and the 1-butanol to react sulfuric acid is added to react with the sodium bromide and combine with the sodium ion producing hydro-bromic acid. Later, when the flask is heated the bromide ion will be able to combine with the four carbon chain of the 1-butanol. During the process of this reaction the reagents were kept cool in an ice bath to avoid the possible evaporation of any of the solution.

“The starting amino acid is highly soluble in the acidic solution of the reaction, the amphoteric nature of L-phenylalanine is apparent at the start of the reaction”. “The L-phenylalanine solution is cooled and then the aqueous NaNO2 solution is added with stirring”. “The reaction mixture begins to form tiny bubbles as the diazonium salt forms and nitrogen gas is liberated by the intramolecular reaction with the carboxylic acid”. “Reaction occurring as the Nitrogen bubbles form”. “This rapid intramolecular reaction reinforces the concepts

Pure ASA crystals are isolated from the solution with a Hirsch Funnel that was used with a filter. The melting point of the pure ASA crystals were calculated in order to calculate of absorbance. Iron (III) salicylate dianion must contain the acidified solution Fe3+ in order to measure the absorbance values. The level of the impurity can

Elijah Brycth B. Jarlos IX-Argon 1. Multicellularity is a condition of an organism to have multicellular cells. An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

The investigation was carried out to identify the presence or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile. A reducing sugar solutions is add inside a test tube with 3 drops to then add 3 drops of benedicts and plane in a water bath.

Tn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.

• Write down the highlighted numbers. Do you observe a pattern? • Does the pattern grow? What is the reason for this? • Write down the last number (say 53).

Specific Aims/Hypothesis(es) to be tested Bacterial Vaginosis (BV) is the most common cause of vaginal symptoms among women of reproductive age, ages 15-44 years. The number of lactobacilli in the vagina of women with BV is significantly lower than that in healthy women. While some women may be asymptomatic, most experience thin, white or yellow abnormal vaginal discharge and malodor, especially after intercourse. Women with BV have an increased risk of many gynecological complications. Bacterial infections have been linked to increased risk factors for many sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) infection.

Azole mainly consists of: (i) Oxygen is referred as oxazole (ii) Sulphur is referred as thiazole and (iii) Nitrogen is referred as pyrazole, imidazoles or imidazolines12. 1, 3-Azoles synthesis12 Scheme 1.1: Synthesis of 1, 3-Azoles by Cyclodehydration of α-acylaminocarbonyl compound12 1.8 OXAZOLE

To analyze the acetanilide product of the reaction, 1H NMR and IR were used. Results, Discussions, and Conclusions In this experiment, acetanilide was synthesized via nucleophilic acyl substitution from both acetic anhydride and aniline. During this reaction, aniline acts as the nucleophile and acyl (CH3CO-) group from acetic anhydride acts as the electrophile.

David Shabazi BIOL476 Cindy Malone 11/1/17 Semaphorin Signaling Regulates Vascular and Hematopoietic Regeneration     Dr. Heather Himburg, Ph.D’s lab utilizes semaphorin 3A signaling to promote bone marrow and vascular recovery following radiation injury. Semaphorin 3A, or SEMA3A for short, is a protein that’s heavily involved in the regulation of patterns in normal neuronal development. Himburg focuses on treating radiation damage in particular because of the following reasons.

Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
